Babysitting my friends chickens, something wrong with their bums

[SydHeron22]

Hi guys,
We currently have our own small flock (3 Chanteclers and a motley crew of pullets) and my friend asked me if she could relocate her chickens to my place while she went away for work for a month. I have her RIRs in a completely different enclosure because I didn't want to spread any diseases to my flock.

She dropped them off yesterday and I noticed they had really "ratty" looking bums, and some frostbite on their cones/waddles (we're in Quebec). Attached are some pictures.
-these birds have been in a coop with a small run attached to it until they moved here (they're basically staying in my straw storage with an impromptu coop, so deep deep bedding, access to outdoor run and quite a bit of windbreak during the day)
-they are 7-9 ish months old if I remember correctly
-they are not lethargic
-they're laying well
-poops look normal
-they’re on good quality food

What do you guys think are going on, and how can I help these poor ladies?

I’m not terribly worried about the frostbite, I’m just going to let it clear up on its own since they’re now protected from wind and draft.

Kinda looks like vent gleet.

I just see dirty vents. I would pull off as many dried droppings and trim any soiled feathers with scissors, just to make sure they can poop normally. If you should see eveidence of vent gleet—inflammed skin,missing feathers, a bad odor with constant drippage— then there could be vent gleet which can be a fungal infection. If you bring a hen into a warm house you can bathe the vent in warm soapy watery, and then use a hair dryer. But no baths if they are not inside.

In winter if they have loose droppings, they can get stuck on feathers and keep building up. The danger is in getting the vent blocked in freezing weather. In warm weather, that can attract flies and a danger of maggots or flystrike.

Thank you! This is super helpful. I do have the ability to bring one-two inside at a time and give them and bath and let them dry for a day or two.
thanks again!!
